The Claim
Nitrate-depleted beetroot juice significantly increases plasma nitrate concentration in both young and older adults, indicating that non-nitrate components of beetroot juice influence nitrate metabolism or retention independent of dietary nitrate intake.
What the research says
Challenges is higher
Challenge is ahead, but a single strong supporting study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Drinking beetroot juice with all nitrate removed still raises nitrate levels in the blood of young and older adults, showing that other compounds in beetroot juice affect how the body handles nitrate.
See the scientific wording
Nitrate-depleted beetroot juice (placebo) significantly increases plasma nitrate concentration in both young and older adults, suggesting that non-nitrate components of beetroot juice—such as phytochemicals—may influence nitrate metabolism or retention, independent of dietary nitrate intake.
When nitrate is consumed, it enters saliva and is converted to nitrite by specific bacteria in the mouth. These bacteria thrive when nitrate is present and outcompete other bacteria that would otherwise turn nitrate into ammonia. The nitrite then enters the bloodstream and is turned into nitric oxide, which relaxes blood vessels and lowers blood pressure.
What the research says
1 studyThe study found that beetroot juice without nitrates didn’t raise nitrate levels in the blood — only the version with added nitrates did. So, the idea that other natural parts of beetroot boost nitrate levels isn’t supported.
